Two identical metal spheres have charges of q1 and q2. They are brought together so they touch, and then they are separated. (a) How is the net charge on the two spheres before they touch related to the net charge after they touch? (b) After they touch and are separated, is the charge on each sphere the same? Why?

(a) Net charge, q1 + q2, stays the same.

(b) Since they are the same size and become equipotential by touching,
the final q1' and q2' are equal. Call that charge q

q1 + q2 = 2q
q1' = q2' = (q1 + q2)/2
